The adsorption of phosphorus (P) onto active soil surfaces plays a pivotal role in immobilizing P, thereby influencing soil fertility and the filter function of soil to protect freshwater systems from eutrophication. Competitive anions, such as organic matter (OM), significantly affect the strength …

Here, we investigated the effects of biogas digestate application on flow pathways and soil properties in a sandy soil aiming at unraveling phosphorus accumulation and depletion processes in fertilized soils. Dye tracer experiments were conducted to visualize and distinguish between various flow pat…

The drilosphere is described as a microbial hotspot in soil, which is rich in labile nutrients. However, phosphorus (P) quality and availability change along the drilosphere from labile organically-bound P in upper layers to immobilized Ca-phosphate with increasing depth. In this study, we postulate…

Heyl K., Garske B., Ekardt F. (2024.0). Using bone char as phosphate recycling fertiliser: an analysis of the new EU Fertilising Products Regulation. Environmental Sciences Europe, 35(1), . doi:10.1186/s12302-023-00819-z

Abstract Background Phosphorus recycling is an important cornerstone of sustainable phosphorus management and required to establish a circular economy in line with the EU Green Deal. Animal bones contain phosphate which can be recovered and processed into bone char. Animal bone char has a fertiliser…

Phosphorus (P) is an indispensable element to all forms of life and its efficient use in fertilizers is one of the conditions for food security. The efficiency of P fertilizers is affected by P mobilization and P fixation, both depending on the P binding strength to soil constituents. This review pr…

AbstractHeterogeneous flow pathways through the soil determine the transport of dissolved and particle-bound nutritional elements like phosphorus (P) to ground and surface waters. This study was designed to understand the spatial patterns of P in agriculturally used soils and the mechanisms causing …

The agronomic value of fertilizer phosphorus (P) in the soil is determined by how it is incorporated and released during aggregate formation and breakdown. These processes play a vital role in P accessibility, storage, and cycling. Bone char (BC) is a promising substitute for phosphorus fertilizer. …

Subsurface losses of colloidal and truly dissolved phosphorus (P) from arable land can cause ecological damage to surface water. To gain deeper knowledge about subsurface particulate P transport from inland sources to brooks, we studied an artificially drained lowland catchment (1550 ha) in north-ea…

Koch S., Rosewig E., Lennartz B. (2023.0). Legacy Phosphorus in Sediments of Lowland Waterways. Environments, 10(3), 43. doi:10.3390/environments10030043

Riverbed sediments in agricultural landscapes are loaded with phosphorus (P). They may act as a source or sink for riverine P, possibly causing harmful algae blooms and eutrophication in streams and receiving water bodies, including coastal waters. In this study, we aimed at identifying the labile, …
